COOKINGr-IBOILER FOR RANGES AND STOVES.

Specification of Letters Patent N0. 21,702, dated October 5, 1868.

T0 all wh0m z't mag c0ncern:

Be itknown (hat I, JOSEPH SCHNABEL, 0f Dayton, in the county 0f Montgomery and State 0f Ohio, have invented a new und useful Improvement in Cooking Vessels and Boilers it'or Stoves or Ranges; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l, is a vertical section 0f my invention taken in the 1ine x, 0a, Fig. 2. Fig. 2, is a horizontal section 0f d0, taken in the 1ine 3 2 Fig.l.

Similar letters of reference indicate COT- responding parts in the two figures.

This invention consists in having the 1ower art of a boiler, kettle, o1 other vessel provided with a series 0f tubes placed around the vessel at its inner side and communicating with the fire when the vesse1 is placed on the stove 01' range, the upper ends of the tubes communioating with a chamber whioh encompasses the upper part of the vesse1, said chamber being connected With the fiue o1 pipe an l formed by having t-he uppe1 pa1t 015 the vessel constructed with double sides.

By this invention the draft 015 the fire is made to pass through the tubes und chamber 0f the vessel und the fire and heated products of combustion brought 1nore directly in contact than usual with the contents 0f the vessel, thereby expediting the heating 01 cooking of the sa1ne and effecting a saving both in time and fue1.

T0 enable those skilled in the a1t to fully 1111derstand and construct myinvention I will proceed to descrlbe it.

A, 1epresents a Wash boiler 01 a cooking vessel which may be constructed 0f sheet metal and externally it may be 0f any 0f the known forma Within the lower pa1t of the boiler A, a series of tubes a, are placed, the lower ends of which pass through to the bottom b, 0f the boiler anal a1e open a1: their lower ends, the ends or orifices of the tubes being flush With the external surface of the bottom b, as shown clearly in Fig. l.

Around the upper art 0f the vessel A, a chambe1 c, is formed. This chamber is 0btained by having the upper pa1t of the vessel constructed with double Walls (Z, (Z, and the upper ends of fihe tubes a, connnunicate with the chamber c, as shown at e. The chamber 0 is connected with a pipe f, which communicates with the smoke pipe g, llbotllbl pipes being provided with dampers Vhen the boiler A, is placed 011 the stove 01 range B, and the damper /1/, in the pipe g, closed, und the da1nper h, in the pipe f, opened, ehe entire blast f10111 the fi1e Will be compelled to pass through the tubes a, a and around the boi1er so as to heat it very quick with very little fuel, und then pass through the pipe f, into the pipe g. \Vhen the blast from t-he fire is no longer needed around fuhe boiler the damper h, may be opened and the da1nper h, closed, und the blast of the fi1e applied to heat an oven 01 for other purposes.

It Will be apparent that my new boiler Will be heated much quicker, Wifl1 fa1 less fuel, and in far 1ess time, than if the fire only czune in cont-act with (hat ortion of th@ heiler which p1ojects below the top of the stove 0r range.

Having described my invention, I c1ai1n- The new 1nanufacture of cooking boiler f01 stows and ranges described, to wit, a cooking boiler provided with perpendicular tubes 01' flues around its sides, f1on1 the bottom upward and opening into a horizontal flue 01 chzunbe1 around the top of the boiler, for the blaze and smoke to pass through substantially 215 described.
